Thomas Kilbride raised the matter in a memorandum this week. The Associated Press obtained a copy from the office of State Sen. Dan Kotowski.

It comes as a US court's June 9 deadline approaches for Illinois lawmakers to pass legislation allowing public possession of weapons.

Kilbride reminds judges that more stringent requirements kicked in this year requiring they report such mental-health rulings to state police. Police had complained in recent years of lax compliance by judges.

Police use the information to do background checks on gun-license applicants.

Kilbride's Wednesday memo to 935 judges says that "recent gun-related tragedies and the current concealed carry debate" have heightened scrutiny over compliance.
